Top five accounting firm RSM US said Thursday it has launched “Ask Luca,” a generative AI tool within RSM Luca, the firm’s digital audit ecosystem, that leaders say will assist its assurance professionals in delivering more efficient, high-quality audits for clients.

Ask Luca provides real-time guidance sourced directly from RSM US’s assurance manuals, practice aids, and technical accounting guides, enabling the firm’s 4,000-plus assurance professionals to quickly access firm-approved information and support their decision-making. It will also advance auditor research by establishing a foundation for future assurance-focused intelligent agents.

As the firm’s audit teams prepare for the upcoming busy season, Ask Luca delivers vetted insights in seconds—reducing research time and helping auditors navigate complex issues more quickly at a time when speed and precision matter most, RSM US said in a Jan. 8 media release.

“RSM Luca, our digital audit ecosystem, is transforming our clients’ experience,” Brandon Rucker, enterprise assurance leader with RSM US, said in a statement. “Leveraging the power of AI and advanced digital tools within RSM Luca, our assurance professionals are able to deliver audits that are both more efficient and of the highest quality. We’re excited about the addition of Ask Luca to our broad suite of digital tools used by our assurance professionals.”

RSM US Assurance Digital Leader Troy Merkel added, “The introduction of Ask Luca further enhances the capabilities of RSM Luca and provides invaluable research capabilities to our assurance professionals as they deliver top-quality audit services to our middle-market clients.”

In addition to leveraging generative AI for improved research capabilities, RSM US said its digital audit ecosystem has transformed other key steps in the firm’s audit process, including:

  • More efficient risk-focused data analysis to understand our client: AI helps auditors to analyze data more quickly and ask more detailed questions to identify and address risks.
  • Enhanced risk assessment: Auditors can review intelligent visualizations of journal entries for smarter insights and anomaly detection.
  • Automated audit evidence reviews: AI enables RSM auditors to efficiently match source documents to support data and uncover insights, which enables them to reach conclusions more quickly.
  • Financial statement review and validation: Augmenting auditors to more efficiently complete required audit procedures.

“While our auditors’ professional judgment, experience, and perspectives are critical to the firm’s audit process, the enhanced capabilities provided through the use of tools powered by generative AI enable our auditors to analyze more comprehensive data and provide deeper insights, leading to an enhanced experience for our clients,” Merkel said.

In June, RSM US announced a $1 billion investment over three years to scale and accelerate the firm’s AI strategy, continuing the digital transformation already underway.
